title: A new monoterpene glycoside from Siparuna thecaphora.
abstract: Phytochemical investigation of the extracts of the leaves of Siparuna thecaphora (Poepp. et Endl.) A. DC. (Siparunaceae) allowed the isolation of one monoterpene glycoside, named trans-thujane-1α,7-diol 1-O-β-D-glucopyranoside (1) along with rutin, quercetin 3-O-β-D-glucopyranoside and 3,4-dihydroxybenzaldehyde. Their structural characterisation was obtained on the basis of extensive spectroscopic analyses, including 1D and 2D NMR experiments and HR-ESI-MS.
